  Iatrogenic Cost Factors Incorporating Mild and Moderate Adverse Events in the Economic Comparison of Aceclofenac and Other NSAIDs

  摘要：

  目标：对乙酰氯芬酸与其他用于治疗包括骨关节炎、类风湿关节炎和强直性脊柱炎在内的常见关节病的非甾体抗炎药（NSAID）在功效和耐受性方面的经济性进行模型化分析。设计：构建了一个决策分析模型，以代表NSAID治疗的临床和经济后果。不依从性、缺乏疗效和不良事件发生率的数据来自比较随机双盲临床试验。使用当地单位治疗成本，并召集专家小组估计资源使用。同时使用经典的综合分析和自举方法来计算NSAID治疗成本的点估计值和95%置信区间。患者和干预措施：数据来自早期荟萃分析中包含的12项随机双盲临床试验。主要结局指标：包括NSAID治疗成本（药品获取成本和处方医生就诊费用）和医源性成本（未达到临床疗效患者的替代治疗成本以及与不良事件相关的医疗访问、治疗、诊断测试和住院费用）以及医源性成本因子（ICF）作为主要结局指标。结果：平均值和95%置信区间显示，除吡罗昔康外，乙酰氯芬酸与其他NSAID在总成本上无统计学显著差异，尽管药品获取成本存在显著差异。乙酰氯芬酸的ICF低于所有其他比较药物，乙酰氯芬酸200 mg/天与双氯芬酸150 mg/天、吲哚美辛100 mg/天、萘普生1000 mg/天、替诺昔康20 mg/天或酮洛芬150 mg/天之间的ICF差异具有统计学意义。结论：这些结果表明，NSAID的比较总体成本与药品获取成本关系不大，而ICF是总体成本最重要的决定因素之一。

• Emerging Role of Pharmacoeconomics in the Research and Development Decision-Making Process

  Objectives: This study examines the organisational structure of pharmacoeconomics departments in major pharmaceutical and biotechnology companies, the impediments to optimal use of pharmacoeconomic evaluations by companies and the integration of pharmacoeconomic analysis with research and development decision making. Data and Methods: The heads of the pharmacoeconomics departments of 40 companies were surveyed on the structure of pharmacoeconomics departments in their companies, the roles that pharmacoeconomic analyses are playing in the new drug development decision-making process, and the initiation of pharmacoeconomic studies during the development process for a random sample of their companies’ investigational new drugs. Results: 45 department heads from 31 parent companies responded to the survey. The pharmacoeconomics function in pharmaceutical and biotechnology companies is relatively new and growing rapidly. Most pharmacoeconomics department heads preferred a different reporting structure than what they currently have and indicated that the strategic role that pharmacoeconomics can play is not well understood within the organisation. Pharmacoeconomic analyses have been increasingly initiated early in clinical development and have been a factor in clinical trial design and in key decisions made during the development process. Conclusions: Given the continued emphasis on containing healthcare costs worldwide, demand will increase for evidence that drugs provide good value for the money spent on them. Companies will likely respond not only with more economic evaluations for purchasers, but also with greater use of pharmacoeconomics early in the development process to aid in rationalising key research and development decisions, and in guiding final pricing decisions and reimbursement planning, thereby improving resource allocations.

  目的：本研究考察了大型制药和生物技术公司药物经济学部门的组织结构，公司对药物经济评估最优使用的障碍以及药物经济学分析与研发决策的整合情况。数据和方法：对40家公司的药物经济学部门负责人进行了调查，内容涉及他们公司药物经济学部门的结构，药物经济学分析在新药研发决策过程中的作用，以及在公司研发的新药中随机抽样进行药物经济学研究的启动情况。结果：31家母公司的45名药物经济学部门负责人对问卷进行了回应。制药和生物技术公司的药物经济学职能相对较新且正在迅速发展。大多数药物经济学部门负责人倾向于与他们目前不同的报告结构，并表明药物经济学在组织内部可以发挥的战略作用未被充分理解。药物经济学分析越来越多地在临床开发的早期阶段启动，并在临床试验设计和开发过程中的关键决策中起到了作用。结论：鉴于全球范围内对控制医疗成本的持续强调，对药物提供良好价值证据的需求将会增加。公司不仅会针对采购商进行更多的经济评估，还可能会在开发过程的早期更广泛地使用药物经济学来协助制定关键的研发决策，并指导最终的定价决策和报销计划，从而优化资源分配。

• Cyclic amide derivatives as potential prodrugs II: N-hydroxymethylsuccinimide- / isatin esters of some NSAIDs as prodrugs with an improved therapeutic index

  Ester prodrugs of aspirin 1a, ibuprofen 1b, naproxen 1c and indomethacin 1d were synthesized using N-Hydroxymethylsuccinimide (HMSI) 3 and N-hydroxymethylisatin (HMIS) 4 as promoieties to reduce their gastrointestinal toxicity and improve bioavailability. Additionally, the kinetics of hydrolysis of the synthesized prodrugs 5a-d and 6a-d were studied at 37 degrees C in non-enzymatic simulated gastric fluid (SGF; hydrochloric acid buffer pH = 1.2); 0.02 M phosphate buffer (pH = 7.4); 80% human plasma and 10% rat liver homogenate. The results indicate higher chemical stability of the ester prodrugs in non-enzymatic SGF (t(1/2) congruent to 6.5-18.6 h) and rapid conversion to the parent drugs in 80% human plasma (t1/2 congruent to 11.4-235 min) as well as in 10% rat liver homogenates (t(1/2) congruent to 12.0-90.0 min). As a general pattern, the HMSI esters 5a-d revealed higher chemical stability than the corresponding HMIS analogues 6a-d. The pH-rate profile of 5c and 6a indicated maximum stability of the former at pH = 1.2-8.0 and of the latter at pH = 1.2-4.0. The distribution coefficient (D-7.4) values of the prodrugs 5a-d, 6a-d and the parent drugs 1a-d in an n-octanol/phosphate buffer (pH =7.4) system indicated enhanced lipophilic properties of the prodrugs. Furthermore, the HMIS ester prodrugs 6a-d are more lipophilic than the corresponding HMSI derivatives 5a-d. In vivo ulcerogenicity studies using scanning electron microscopy on stomach specimens of rats treated with an oral dose for 4 d revealed that the synthesized ester prodrugs are significantly less irritating to gastric mucosa than the parent drugs. These results suggested HMSI and/or HMIS esters possess good potential as prodrugs with an improved therapeutic index for oral delivery of NSAIDs.
